Oil pressure low when temp.up

Hi it sounds like you have either worn piston rings /dirty air cleaner /the wrong grade oil in engine as if your temp goes up to high above normal and you have a 10w 40, then change to 30 w 50 and change the oil filter and thermostat,as your sump is also your gear box and you have a gear box heating up the oil just standing still, so do this first and let me know. as piston rings and valve guides are a big and costly job.

this sounds like oil rings are worn or broken and that would need all rings replacing, have you done a compression test? if not it would be helpful to do one and compare when hot and cold,

Austin healey hot start problem

Most of the time this is due to the pistons in the CV carbs not rising with the increase in intake vac. Clean your carbs and this allows the carb pistons to rise with inflow allowing a richer fuel flow.
If that doesn't help, read your plugs. Are they burning a light tan? If not, you may have some compression/valve problems. Do a compression test on each cylinder, Should be over 100psi straight across +or- 10%. Great Car....happy motoring.

Is it easier to replace wheel arches on a austin

It is unusual to have the arches rot out (about the only part that is usually sound) I know the inners are available and inexpensive, probably easier to weld in new ones that patch up the old, certainly better for the car.
